Abstract (en)
[origin: US2012323379A1] The disclosed embodiments include a pressure balance valve that solves one or more problems associated with existing designs. For example, in one embodiment, a pressure balancing valve assembly is disclosed that provides a low cost frictionless assembly that is constructed to not seal the leak path between an inlet port and an outlet port. Instead, this leak path is minimized with small angle tapered plunger and a precision bored annulus to provide a defined area for the pressure drop to occur and to limit the flow from the inlet to the outlet.
